The 10B(n,$alpha$)7Li cross sections at ultra-low energy through the Trojan Horse Method applied to the 2H(10B,$alpha^{7}$7Li)1H

In the framework of the experimental campaign of the ($ p,\alpha$) and ($ n,\alpha$) reactions cross sections measurement involving the 10, 11B isotopes, different ($ n,\alpha$) cross section measurements have been performed at ultra-low energy. In this work, the 10B(n,$ \alpha$)7Li reaction was investigated through the Trojan Horse Method, by means of the Quasi-Free (QF) 2H(10B,$ \alpha^{7}$Li)1H reaction at 30 MeV of beam energy. As in the standard THM approach, the measurement has been performed in inverse kinematics using a 10B beam. The excitation function of the 10B(n,$ \alpha$)7Li reaction has been measured at a center-of-mass energy between 0 and 700 keV. The data were compared with the existing experimental ones. Even if the energy resolution of the present experiment did not allow a separation between the channels ($ n,\alpha_0$) and ($ n,\alpha_1$) the low energy cross section and the angular distribution are presented, pointing out once more the ability of the method in studying neutron induced reactions using deuteron as source of virtual neutrons.
